Abstract
With the development of release of heavy metals into the environment is increasing. The abundant use and increase the level of concern is serious. Biotechnology, bioremoval heavy metals from industrial wastewater by using microorganisms' ability to be an efficient, environmentally friendly and developing effective. Identify bacteria resistant to toxic metals that have the potential in this area are technically complex and useful. The use of hallophilic bacteria due to having special features, high power stability important in biological cleaning of metal compounds in natural environments play. Biological removal of toxic metal cadmium with high, environmental movement as an important field of biotechnology. Optimization of environmental conditions whose removal increases the efficiency should be considered further. The aim of this study reviews the removal of cadmium by bio-dispersion. And the impact of environmental factors on biological uptake of heavy and compare them with other bioabsorbents.
